RFR: 8333248: VectorGatherMaskFoldingTest.java failed when maximum vector bits is 64 [v3]

[Gui Cao]

> Hi, VectorGatherMaskFoldingTest.java Test fails when max vector bits is 64, when max vector bits is 64, LongVector.SPECIES_MAX.length() and DoubleVector.SPECIES_MAX.length() is 1. 
> 
> We can reproduce this problem in two ways:
> 1. We can use riscv without rvv1.0 board to reproduce this problem
> 2. Run VectorGatherMaskFoldingTest.java on aarch64 client mode without `-XX:+IncrementalInlineForceCleanup` Option,  the `-XX:+IncrementalInlineForceCleanup` is C2 Option, so we need to remove this Option from the VectorGatherMaskFoldingTest.main method. error message:
